BACKGROUND OF THE INVENTION Field of the Art

The disclosure relates to the field of computer systems, and more particularly to the field of cybersecurity and threat analytics.

Discussion of the State of the Art

In the field of product liability underwriting, there has existed for over 125 years a product safety testing institute called the Underwriters Laboratories. The original purpose of the Underwriters Laboratories was to test and certify electrical appliances for fire safety purposes, so that fire insurance underwriters had reliable information on which to base their fire insurance policy terms. The scope of the UL has expanded to include other types of mechanical and electrical appliances, and many other testing companies exist that perform a similar function for mechanical and electrical appliances. However, there is currently no similar standard for testing, certifying, and/or rating computer systems for cybersecurity purposes.

What is needed is a system and method for holistic computer system cybersecurity evaluation and rating that takes into account the operation of the entire computer system environment comprising hardware, software, and the operating system.

DETAILED DESCRIPTION

The inventor has conceived, and reduced to practice, a system and method for holistic network cybersecurity evaluation and risk rating that takes into account the operation of the entire target network environment comprising hardware, software, operating systems, and network connections. Not only are the hardware, software, operating system, and network evaluated separately for cybersecurity concerns, their interaction and operation as a whole are also evaluated and scored. The results of such analyses may be used, for example, by underwriters of cybersecurity insurance policies to determine policy terms and rates.

Insurance underwriters needs accurate risk information in order to properly establish policy terms and set rates. For most insurance fields, there reliable data exists for underwriters to use in making such decisions. In the field of life insurance, for example, very reliable and accurate data exist regarding life expectancies based on an individual's age and health profile. For fire insurance, reliable and accurate data exist regarding fire frequency, severity, and the value of property damaged. In the field of product liability insurance, a testing industry has existed for decades to test mechanical and electrical appliances, and rate or certify them according to various criteria, precisely for the purpose of providing data regarding the safety of those items. As mentioned above, Underwriters Laboratory has been in existence for 125 years, and was originally formed to provide fire insurance underwriters with reliable data regarding electrical appliances.

Despite having such testing available in other industries, no testing, certifying, and/or rating exists for computer systems for cybersecurity purposes. Computers have become ubiquitous in both personal and business use, and the potential for economic, privacy, and other harms due to cybersecurity attacks is tremendous. Insurance underwriters have begun offering cybersecurity insurance policies in recent years. Yet, while there are general data regarding the number and types of cybersecurity attacks, and related losses in the case of successful attacks, there is no standard system or method for establishing, rating, or scoring the security of computer systems as a whole. Insurers need such data to adequately establish policy terms and set rates. There is also the possibility that computer hardware manufacturers, software developers, and operating system developers could be held liable for failure to adequately design and/or build their products with sufficient cybersecurity protections. In the event that product liability evolves in that direction, product liability insurance underwriters will need accurate and reliable data on which to base their policies.

One or more different aspects may be described in the present application. Further, for one or more of the aspects described herein, numerous alternative arrangements may be described; it should be appreciated that these are presented for illustrative purposes only and are not limiting of the aspects contained herein or the claims presented herein in any way. One or more of the arrangements may be widely applicable to numerous aspects, as may be readily apparent from the disclosure. In general, arrangements are described in sufficient detail to enable those skilled in the art to practice one or more of the aspects, and it should be appreciated that other arrangements may be utilized and that structural, logical, software, electrical and other changes may be made without departing from the scope of the particular aspects. Particular features of one or more of the aspects described herein may be described with reference to one or more particular aspects or figures that form a part of the present disclosure, and in which are shown, by way of illustration, specific arrangements of one or more of the aspects. It should be appreciated, however, that such features are not limited to usage in the one or more particular aspects or figures with reference to which they are described. The present disclosure is neither a literal description of all arrangements of one or more of the aspects nor a listing of features of one or more of the aspects that must be present in all arrangements.

Headings of sections provided in this patent application and the title of this patent application are for convenience only, and are not to be taken as limiting the disclosure in any way.

Devices that are in communication with each other need not be in continuous communication with each other, unless expressly specified otherwise. In addition, devices that are in communication with each other may communicate directly or indirectly through one or more communication means or intermediaries, logical or physical.

A description of an aspect with several components in communication with each other does not imply that all such components are required. To the contrary, a variety of optional components may be described to illustrate a wide variety of possible aspects and in order to more fully illustrate one or more aspects. Similarly, although process steps, method steps, algorithms or the like may be described in a sequential order, such processes, methods and algorithms may generally be configured to work in alternate orders, unless specifically stated to the contrary. In other words, any sequence or order of steps that may be described in this patent application does not, in and of itself, indicate a requirement that the steps be performed in that order. The steps of described processes may be performed in any order practical. Further, some steps may be performed simultaneously despite being described or implied as occurring non-simultaneously (e.g., because one step is described after the other step). Moreover, the illustration of a process by its depiction in a drawing does not imply that the illustrated process is exclusive of other variations and modifications thereto, does not imply that the illustrated process or any of its steps are necessary to one or more of the aspects, and does not imply that the illustrated process is preferred. Also, steps are generally described once per aspect, but this does not mean they must occur once, or that they may only occur once each time a process, method, or algorithm is carried out or executed. Some steps may be omitted in some aspects or some occurrences, or some steps may be executed more than once in a given aspect or occurrence.

When a single device or article is described herein, it will be readily apparent that more than one device or article may be used in place of a single device or article. Similarly, where more than one device or article is described herein, it will be readily apparent that a single device or article may be used in place of the more than one device or article.

The functionality or the features of a device may be alternatively embodied by one or more other devices that are not explicitly described as having such functionality or features. Thus, other aspects need not include the device itself.

Techniques and mechanisms described or referenced herein will sometimes be described in singular form for clarity. However, it should be appreciated that particular aspects may include multiple iterations of a technique or multiple instantiations of a mechanism unless noted otherwise. Process descriptions or blocks in figures should be understood as representing modules, segments, or portions of code which include one or more executable instructions for implementing specific logical functions or steps in the process. Alternate implementations are included within the scope of various aspects in which, for example, functions may be executed out of order from that shown or discussed, including substantially concurrently or in reverse order, depending on the functionality involved, as would be understood by those having ordinary skill in the art.

Definitions

As used herein, a “swimlane” is a communication channel between a time series sensor data reception and apportioning device and a data store meant to hold the apportioned data time series sensor data. A swimlane is able to move a specific, finite amount of data between the two devices. For example, a single swimlane might reliably carry and have incorporated into the data store, the data equivalent of 5 seconds worth of data from 10 sensors in 5 seconds, this being its capacity. Attempts to place 5 seconds worth of data received from 6 sensors using one swimlane would result in data loss.

As used herein, a “metaswimlane” is an as-needed logical combination of transfer capacity of two or more real swimlanes that is transparent to the requesting process. Sensor studies where the amount of data received per unit time is expected to be highly heterogeneous over time may be initiated to use metaswimlanes. Using the example used above that a single real swimlane can transfer and incorporate the 5 seconds worth of data of 10 sensors without data loss, the sudden receipt of incoming sensor data from 13 sensors during a 5 second interval would cause the system to create a two swimlane metaswimlane to accommodate the standard 10 sensors of data in one real swimlane and the 3 sensor data overage in the second, transparently added real swimlane, however no changes to the data receipt logic would be needed as the data reception and apportionment device would add the additional real swimlane transparently.

Conceptual Architecture

FIG. 1 is a diagram of an exemplary architecture of a system for the capture and storage of time series data from sensors with heterogeneous reporting profiles according to a preferred aspect of the invention 100. In this embodiment, a plurality of sensor devices 110 a-n stream data to a collection device, in this case a web server acting as a network gateway 115. These sensors 110 a-n can be of several forms, some non-exhaustive examples being: physical sensors measuring humidity, pressure, temperature, orientation, and presence of a gas; or virtual such as programming measuring a level of network traffic, memory usage in a controller, and number of times the word “refill” is used in a stream of email messages on a particular network segment, to name a small few of the many diverse forms known to the art. In the embodiment, the sensor data is passed without transformation to the data management engine 120, where it is aggregated and organized for storage in a specific type of data store 125 designed to handle the multidimensional time series data resultant from sensor data. Raw sensor data can exhibit highly different delivery characteristics. Some sensor sets may deliver low to moderate volumes of data continuously. It would be infeasible to attempt to store the data in this continuous fashion to a data store as attempting to assign identifying keys and store real time data from multiple sensors would invariably lead to significant data loss. In this circumstance, the data stream management engine 120 would hold incoming data in memory, keeping only the parameters, or “dimensions” from within the larger sensor stream that are pre-decided by the administrator of the study as important and instructions to store them transmitted from the administration device 112. The data stream management engine 120 would then aggregate the data from multiple individual sensors and apportion that data at a predetermined interval, for example, every 10 seconds, using the timestamp as the key when storing the data to a multidimensional time series data store over a single swimlane of sufficient size. This highly ordered delivery of a foreseeable amount of data per unit time is particularly amenable to data capture and storage but patterns where delivery of data from sensors occurs irregularly and the amount of data is extremely heterogeneous are quite prevalent. In these situations, the data stream management engine cannot successfully use strictly single time interval over a single swimlane mode of data storage. In addition to the single time interval method the invention also can make use of event based storage triggers where a predetermined number of data receipt events, as set at the administration device 112, triggers transfer of a data block consisting of the apportioned number of events as one dimension and a number of sensor ids as the other. In the embodiment, the system time at commitment or a time stamp that is part of the sensor data received is used as the key for the data block value of the value-key pair. The invention can also accept a raw data stream with commitment occurring when the accumulated stream data reaches a predesigned size set at the administration device 112.

It is also likely that that during times of heavy reporting from a moderate to large array of sensors, the instantaneous load of data to be committed will exceed what can be reliably transferred over a single swimlane. The embodiment of the invention can, if capture parameters pre-set at the administration device 112, combine the data movement capacity of two or more swimlanes, the combined bandwidth dubbed a metaswimlane, transparently to the committing process, to accommodate the influx of data in need of commitment. All sensor data, regardless of delivery circumstances are stored in a multidimensional time series data store 125 which is designed for very low overhead and rapid data storage and minimal maintenance needs to sap resources. The embodiment uses a key-value pair data store examples of which are Riak, Redis and Berkeley DB for their low overhead and speed, although the invention is not specifically tied to a single data store type to the exclusion of others known in the art should another data store with better response and feature characteristics emerge. Due to factors easily surmised by those knowledgeable in the art, data store commitment reliability is dependent on data store data size under the conditions intrinsic to time series sensor data analysis. The number of data records must be kept relatively low for the herein disclosed purpose. As an example, one group of developers restrict the size of their multidimensional time series key-value pair data store to approximately 8.64×10⁴ records, equivalent to 24 hours of 1 second interval sensor readings or 60 days of 1 minute interval readings. In this development system the oldest data is deleted from the data store and lost. This loss of data is acceptable under development conditions but in a production environment, the loss of the older data is almost always significant and unacceptable. The invention accounts for this need to retain older data by stipulating that aged data be placed in long term storage. In the embodiment, the archival storage is included 130. This archival storage might be locally provided by the user, might be cloud based such as that offered by Amazon Web Services or Google or could be any other available very large capacity storage method known to those skilled in the art.

Reliably capturing and storing sensor data as well as providing for longer term, offline, storage of the data, while important, is only an exercise without methods to repetitively retrieve and analyze most likely differing but specific sets of data over time. The invention provides for this requirement with a robust query language that both provides straightforward language to retrieve data sets bounded by multiple parameters, but to then invoke several transformations on that data set prior to output. In the embodiment isolation of desired data sets and transformations applied to that data occurs using pre-defined query commands issued from the administration device 112 and acted upon within the database by the structured query interpreter 135. Below is a highly simplified example statement to illustrate the method by which a very small number of options that are available using the structured query interpreter 135 might be accessed.

SELECT [STREAMING|EVENTS] data_spec FROM [unit] timestamp TO timestamp GROUPBY (sensor_id, identifier) FILTER [filter_identifier] FORMAT [sensor [AS identifier] [, sensor [AS identifier]] . . . ] (TEXT|JSON|FUNNEL|KML|GEOJSON|TOPOJSON);

Here “data_spec” might be replaced by a list of individual sensors from a larger array of sensors and each sensor in the list might be given a human readable identifier in the format “sensor AS identifier”. “unit” allows the researcher to assign a periodicity for the sensor data such as second (s), minute (m), hour (h). One or more transformational filters, which include but a not limited to: mean, median, variance, standard deviation, standard linear interpolation, or Kalman filtering and smoothing, may be applied and then data formatted in one or more formats examples of with are text, JSON, KML, GEOJSON and TOPOJSON among others known to the art, depending on the intended use of the data.

FIG. 2 is a diagram of an exemplary architecture of a business operating system 200 according to a preferred aspect. Client access to the system 205 both for system control and for interaction with system output such as automated predictive decision making and planning and alternate pathway simulations, occurs through the system's highly distributed, very high bandwidth cloud interface 210 which is application driven through the use of the Scala/Lift development environment and web interaction operation mediated by AWS ELASTIC BEANSTALK™, both used for standards compliance and ease of development. Much of the business data analyzed by the system both from sources within the confines of the client business, and from cloud based sources, also enter the system through the cloud interface 210, data being passed to the analysis and transformation components of the system, the directed computational graph module 255, high volume web crawling module 215 and multidimensional time series database 220. The directed computational graph retrieves one or more streams of data from a plurality of sources, which includes, but is in no way not limited to, a number of physical sensors, web based questionnaires and surveys, monitoring of electronic infrastructure, crowd sourcing campaigns, and human input device information. Within the directed computational graph, data may be split into two identical streams, wherein one sub-stream may be sent for batch processing and storage while the other sub-stream may be reformatted for transformation pipeline analysis. The data is then transferred to general transformer service 260 for linear data transformation as part of analysis or decomposable transformer service 250 for branching or iterative transformations that are part of analysis. The directed computational graph 255 represents all data as directed graphs where the transformations are nodes and the result messages between transformations edges of the graph. These graphs which contain considerable intermediate transformation data are stored and further analyzed within graph stack module 245. High volume web crawling module 215 uses multiple server hosted preprogrammed web spiders to find and retrieve data of interest from web based sources that are not well tagged by conventional web crawling technology. Multiple dimension time series database module 220 receives data from a large plurality of sensors that may be of several different types. The module is designed to accommodate irregular and high volume surges by dynamically allotting network bandwidth and server processing channels to process the incoming data. Data retrieved by the multidimensional time series database 220 and the high volume web crawling module 215 may be further analyzed and transformed into task optimized results by the directed computational graph 255 and associated general transformer service 250 and decomposable transformer service 260 modules.

Results of the transformative analysis process may then be combined with further client directives, additional business rules and practices relevant to the analysis and situational information external to the already available data in the automated planning service module 230 which also runs powerful predictive statistics functions and machine learning algorithms to allow future trends and outcomes to be rapidly forecast based upon the current system derived results and choosing each a plurality of possible business decisions. Using all available data, the automated planning service module 230 may propose business decisions most likely to result is the most favorable business outcome with a usably high level of certainty. Closely related to the automated planning service module in the use of system derived results in conjunction with possible externally supplied additional information in the assistance of end user business decision making, the business outcome simulation module 225 coupled with the end user facing observation and state estimation service 240 allows business decision makers to investigate the probable outcomes of choosing one pending course of action over another based upon analysis of the current available data. For example, the pipelines operations department has reported a very small reduction in crude oil pressure in a section of pipeline in a highly remote section of territory. Many believe the issue is entirely due to a fouled, possibly failing flow sensor, others believe that it is a proximal upstream pump that may have foreign material stuck in it. Correction of both of these possibilities is to increase the output of the effected pump to hopefully clean out it or the fouled sensor. A failing sensor will have to be replaced at the next maintenance cycle. A few, however, feel that the pressure drop is due to a break in the pipeline, probably small at this point, but even so, crude oil is leaking and the remedy for the fouled sensor or pump option could make the leak much worse and waste much time afterwards. The company does have a contractor about 8 hours away, or could rent satellite time to look but both of those are expensive for a probable sensor issue, significantly less than cleaning up an oil spill though and then with significant negative public exposure. These sensor issues have happened before and the business operating system 200 has data from them, which no one really studied due to the great volume of columnar figures, so the alternative courses 225, 240 of action are run. The system, based on all available data predicts that the fouled sensor or pump are unlikely the root cause this time due to other available data and the contractor is dispatched. She finds a small breach in the pipeline. There will be a small cleanup and the pipeline needs to be shut down for repair but multiple tens of millions of dollars have been saved. This is just one example of a great many of the possible use of the business operating system, those knowledgeable in the art will easily formulate more.

FIG. 3 is a system diagram, illustrating the connections between crucial components, according to an aspect of the invention. Core components include a scheduling task engine 310 which will run any processes and continue with any steps desired by the client, as described in further methods and diagrams in the disclosure. Tasks may be scheduled to run at specific times, or run for certain given amounts of time, which is commonplace for task scheduling software and systems in the art. This task engine 310 is then connected to the internet, and possibly to a single or plurality of local Multi-Dimensional Time-Series Databases (MDTSDB) 125. It is also possible to be connected to remotely hosted and controlled MDTSDB's 125 through the Internet, the physical location or proximity of the MDTSDB for this disclosure not being a limiting factor. In such cases as the MDTSDB 125 is not hosted locally, it must also maintain a connection to the Internet or another form of network for communication with the task engine 310. Device endpoints 330, especially Internet-of-Things (IoT) devices, are also by definition connected to the internet, and in methods described in later figures will be used for cybersecurity analysis and risk assessment. The task engine 310 which will perform the scheduling and running of the methods described herein also maintains a connection to the scoring engine 320, which will be used to evaluate data gathered from the analysis and reconnaissance tasks run by the task scheduling engine 310.

FIG. 4 is a system diagram illustrating connections between important components for analyzing software and network-connected endpoints. A business operating system (OS) 410 operates on a system outlined in FIG. 2 , with key components including the OS kernel 411 which is a component common to all operating systems, and on that kernel, aside from other pieces of software for other purposes, are two important engines, a binary file translator 412 and a sandbox simulation environment 413. A binary file translator 412 may convert any given file or set of input data into executable machine code, and a sandbox environment 413 is a simulation environment which may execute machine code in a closed-off environment, similar in purpose to an experiment carried out in a sealed room. This may be done in a variety of ways, including emulator software for specific system architectures and open source code executors. Such an OS 410 would be connected to a database 420, which may be formatted in Structured Query Language (SQL) form, formatted raw text, encrypted text, or no-SQL forms, and may be used in conjunction with management software such as APACHE HADOOP™ for increased performance. This connection may be either a direct physical connection, or the OS 410 and database 420 may be located on the same physical machine, or they may be connected over a network 430, including the Internet or other kinds of computer networks. Similarly, a score generation system 440 may be connected to the operating system 410, either through a network 430, or through a direct physical connection, or by operating on the same machine as the operating system 410 itself. This scoring engine is used in later figures to prioritize software vulnerabilities and exploits. A variety of device endpoints 450 may be connected over a network 430 and accessible to the operating system 410, by use of endpoint instrumentation such as OSQUERY™, and these device endpoints may be varied in form, including laptop computers, desktops, mobile phones, and various Internet of Things (IoT) devices. It is possible for only one endpoint 451 to be connected, and it is similarly possible for a multitude of various different endpoints to be connected 452, 453.

FIG. 5 is a method diagram illustrating important steps in detecting and analyzing software exploits or vulnerabilities of the invention. A file that is targeted for analysis may be translated into executable binary code 510 by use of a binary translation engine 412, and this executable binary code may then be transferred to a sandbox environment 520, 413, for analysis. The specific environment in use may vary depending on the code generated by the binary translation engine 412, including hardware emulators, operating system emulators, and more. The executable binary code is then executed in the simulated environment 530, and the operating system then may examine the executing software for any irregularities 540. Irregularities include activities not normally performed by benign software including memory scanning, and deletion of the executable binary during execution (but the executing code remaining in memory), which are known patterns of malware to avoid detection and elimination. Attempted access of system files, permissions, settings, or network adapters in suspicious ways may also be classified as “irregularities,” though the characterization and scope of what the operating system 410 looks for may grow and change over time as cybersecurity and malware both advance. The operating system may also probe the executing software for vulnerabilities and exploits 550, which will often be known forms of attack, such as the Heartbleed exploit in OPENSSL™, and are known to many skilled in the art of cybersecurity. The types of vulnerabilities and exploits probed for may change and grow as cybersecurity advances as a field. The operating system 410 may then learn new behaviors 560 according to the results of analysis, for example the operating system 410 may probe for the Heartbleed exploit 550 in a piece of software to see if it is prone to that exploit, and if it is, the operating system may be trained look for similar execution patterns in future software analyses to determine if a piece of software is likely to be vulnerable to the same exploit, an example of reinforcement learning 560. This may be achieved in numerous ways common in the art including neural networks, a basic decision weight system, and more, all common concepts in computer science and software development as a whole.

FIG. 6 is a method diagram illustrating the use of advanced endpoint instrumentation to collect data on endpoint devices across a network. First, the network endpoint must have the instrumentation installed before it can be utilized 610, and some common instrumentations include OSQUERY™ and open source fleet management software including “doorman,” an open source fleet management suite for OSQUERY™. Software such as OSQUERY™ allows devices to be queried and scanned similar to data files or databases, so that property and/or relational data about the device may be scanned easily and swiftly by an authorized user, in this case the business operating system 410. Once a form of instrumentation software is installed onto the endpoints used in the system 610, device data may be remotely queried by the business operating system 620, similar to a database query over the internet. Device data is then sent back to the machine hosting the business operating system 630, which is then analyzed for potential vulnerability profiling 640. For example, certain phones that may be used in this system have various exploits and vulnerabilities that are exclusive to each other, as do many older operating systems for personal computers, and this information would be able to be queried for analysis 640.

FIG. 7 is a method diagram illustrating the prioritization of software flaws and exploits according to a preferred aspect. Vulnerabilities and exploits found in software executed in the sandbox environment 413 are relayed to the scoring engine 440, 710, which may be either a connection over a network 430 or a direct physical connection between only the two machines, or both the scoring engine 440 and operating system 410 may be operating on the same computing device. The vulnerabilities and exploits found in the software execution may then be scored by the scoring engine 720, which will assign a higher risk level to exploits which may involve deleting system critical files, highly evasive code techniques which may evade most forms of antivirus software, and more, using a scoring methodology which may be specified and changed at any time by the user of the software. The scoring methodology may be arbitrary or follow any given set of rules specified by the user of the software, the importance of this being that as cybersecurity and malware advance, the need for a changing and advancing ranking of threats is obvious and immediate—what was considered a horrible computer virus 15 years ago may be easily detectable today, and similarly, what is considered incredibly high-risk today may be of no consequence to antivirus software 15 years from now, and therefore be categorized as a low threat to most devices. Regardless, at the time of execution, the scoring engine 440 will then inform the operating system 410 of a ranking of the found vulnerabilities or threats in the executed software 730, ranking the issues found from most dangerous or pressing, to least dangerous or pressing.

FIG. 8 is a method diagram illustrating the basic steps for patching exploits and vulnerabilities in analyzed software, according to an aspect. After receiving a list of exploitable or dangerous behaviors from a simulated piece of software 730, the business operating system 410 will attempt to make any of various changes or limitations implementable at the kernel level to the software's execution 810, to “patch” the vulnerability or threat. Such measures may include techniques such as Address Space Layout Randomization (ASLR), a memory protection process which randomizes the location in computer memory where system executable code is loaded, and measures used to patch undesirable behavior or vulnerabilities may include other techniques including data execution prevention (DEP), which prevents certain sectors of memory from being executed, protecting potentially important system processes from attack. There are a large variety of security measures that may be implemented in an effort to patch software behavior, and the importance of noting that it is to patch behavior is that the system is not analyzing the code itself and re-writing code in software to be permanently patched, but rather it is changing system behavior based on observed software behavior to protect against any behavior that is either vulnerable to exploitation, or is itself malware. If an implemented patch does not solve the undesired behavior or vulnerability in the tested software, and is deemed a failure, then the operating system 410 may learn through reinforcement learning algorithms to try different measures first, if the same behavior occurs during analysis of a different piece of software 830. If the implemented patch or hotfix does stop the undesirable behavior, and is deemed a success, the operating system 410 learns, conversely to the previous situation, that this patch is an effective measure against such behaviors, and will try it sooner than other (either untested or possibly ineffective) measures that it may have tried 820. This patch or enhancement to the software's functionality is then sent to the endpoint 450, 840 which hosted this file or piece of software that was being analyzed, so that the undesired behavior or vulnerability is effectively mitigated.

FIG. 9 is a block diagram showing an exemplary overall system architecture for a holistic computer system cybersecurity evaluation and scoring system 900. In this embodiment, the system comprises a system definition portal 901, a software analyzer 1000, a hardware analyzer 1100, an operating system analyzer 1200, and a scoring engine 1300. The system definition portal 901 provides the means for a user to define the system to be tested (also known as the “system under test”) in terms of its hardware, software, and operating system components. The software analyzer 1000 receives the definition of the software component of the system under test and analyzes it for cybersecurity issues. The hardware analyzer 1100 receives the definition of the hardware component of the system under test and analyzes it for cybersecurity issues. The operating system analyzer 1200 receives the definition of the software component of the system under test and analyzes it for cybersecurity issues. The scoring engine 1000 receives the analyses from the software analyzer 1000, hardware analyzer 1100, and operating system analyzer 1200, performs additional checking and testing of the system under test as a whole, and assigns a cybersecurity rating or score to the system under test as a whole computing environment. Note that an operating system is a type of software, so references to software may include operating systems where the context allows.

With respect to the system definition portal 901, in this embodiment the system definition portal 901 is a stand-alone portal allowing for definition of the entire system under test, but in other embodiments, it may be simply be an input component of the software analyzer 1000, hardware analyzer 1100, and operating system (OS) analyzer 1200. Each of the software, hardware, and operating components of the system under test can be defined in several ways. One primary method of definition is specification of the component's parameters. For the hardware component, for example, the hardware may be defined by specifying the particular components that make up the hardware (e.g., the central processing unit (CPU), memory, storage, system bus, etc.), including details such as the manufacturer, date of manufacture, model number, serial number, etc., from which the performance characteristics of each part can be obtained. Alternatively, the hardware may be defined directly in terms of performance characteristics, for example specifying the bit width (or word length) of the architecture (e.g., 32-bit, 64-bit, etc.), the processor clock speed, the bus speed, and other characteristics that determine the hardware's performance. For hardware, in particular, definitions by specification may be useful as the actual hardware may not be available or may difficult to obtain, yet can often be emulated using an emulator or virtual machine. Similar definitions by specification can be made of software and operating systems, for example specifying the software name, version, etc., from which operating characteristics may be identified, or by directly specifying the operating characteristics. While it is possible to emulate or simulate the operation of software, this is typically not done as the software is usually readily available. A second method of definition is provision of the actual software, hardware, and/or OS to be tested. For example, software and operating systems can be uploaded, the actual hardware to be tested may be provided, and in some cases the entire system may be provided for testing with the software and operating system already installed on the hardware. Where physical hardware is used to define the hardware under test, the actual physical computing device may be used as the hardware under test. In some cases, the physical hardware may be physically transported (e.g., delivery, drobox, etc.), while in other cases the physical hardware may be accessed and operated locally (i.e., onsite), while in yet other cases the physical hardware may be accessed and operated remotely (e.g., via a terminal associated with the physical hardware, remote device control using a different computer, screensharing, etc.).

A further aspect of the system definition portal 901 is that information about the usage of the computer system under test may be specified for scoring purposes. For example, the domain in which the computer system will be used, the use to which the computer system will be put, the criticality of the computer system to overall operations of a business or larger network of computers, and the magnitude of losses that would occur if the system was compromised may all be entered to more precisely define the parameters of the evaluation and scoring. This list is not intended to be exhaustive, and other such information and parameters may be used.

FIG. 10 is a block diagram showing an exemplary architecture for a software analyzer 1000 for a holistic computer system cybersecurity evaluation and scoring system. In this embodiment, the software analyzer 1000 comprises a software definition portal 1010, a source code analyzer 1020, a compiler 1030, a compiled code analyzer 1040, and one or more database resources 1050. The software definition portal 1010 receives either uncompiled, human-readable source code 1011, or compiled machine-readable binary code 1012 to define the software component of the system under test. In this example, definition by specification is not used, and it is assumed that the software to be tested is provided. If source code 1011 is provided, the software definition portal 1010 forwards the source code 1011 to the source code analyzer 1020 for coding analysis prior to compiling.

The source code analyzer 1020 comprises a coding library analyzer 1021 and a coding complexity analyzer 1022. The coding library analyzer searches the code for functions, classes, modules, routines, system calls, and other portions of code that rely on or incorporate code contained in code libraries developed by a different entity than the entity that developed the software under test. Code libraries are collections of code that have been developed for use in specific circumstances, such as standardized classes developed for an object-oriented coding language (e.g., C++, JAVA, etc.), tools developed for a particular integrated development environment (e.g., Code::Blocks, Eclipse), common libraries for interacting with the operating system, templates, subroutines, etc., that are designed to help speed up, standardize, or make easier the coding of applications. The code in such libraries is of varying quality, complexity, usability, security, etc. Code in open source libraries is particularly variable, depending on the skill and knowledge of the (usually part-time, volunteer) contributors, and subject to deprecation if maintenance of the code slows or stops. The source code analyzer 1021 uses this information to determine which code libraries are used, what code from the libraries is used, and the security level of that code, and the security level of the source code 1011 as a result of using code from those libraries. The coding library analyzer 1021 may access one or more database resources 1050 such as open source libraries 1051 a, malware databases 1051 b, lists of deprecated or out of date software, etc.

The coding complexity analyzer 1022 analyzes the level of additional cybersecurity risk due to the complexity of the code. As an illustrative example, the cyclomatic complexity of a particular software package is a strong indicator of the number of errors that are likely to be in the code. The cyclomatic complexity of a piece of software is a quantitative measure of the number of linearly independent paths through a program's source code.

After the source code analyzer 1020 has completed analysis of the source code 1011, the source code 1011 is compiled by a compiler 1030 for operational testing. The compiler 1030 used will depend on the language in which the source code 1011 was written. Many different compilers 1030 may be available for any given coding language.

Binary code 1012, whether received directly by the software definition portal 1010 or compiled by the compiler 1030 from source code 1011, is sent to a compiled code analyzer 1040 which analyzes the software while it is in operation (i.e., running) on hardware under an operating system. While the software is running, a function extractor 1041 monitors which operations are performed by the software, the order of such operations, and which system resources are accessed by the software, which can disclose the functions, subroutines, etc., that are being executed by the compiled code. The characteristics of those functions, subroutines, etc., can be matched to similar functions, subroutines, etc., in coding libraries and such that the function extractor can identify code from code libraries that are contained in, and being used by, the compiled software. This information about the binary code 1012 can be sent to the coding library analyzer 1021 for analysis (typically where such analysis has not already been performed by the source code analyzer 1020). Further, a low-level system access detector 1043 will simultaneously monitor the running software to identify access of, or attempted access of, low-level system resources (e.g., kernel, stack, heap, etc.) that may indicate cybersecurity concerns. A compiler identifier 1044 can be used to identify the compiler used to create the binary code 1012 and certain information about the settings used when during compilation. In many cases, compilers embed information in the compiled code such as the compiler identification, version number, settings, etc., in a comment section composed of ASCII text. The binary can be scanned for such textual information. Alternatively, the binary file can be “decompiled” or “disassembled” in an attempt to match the inputs and outputs of known compilers. The compiler identifier 1044 may access one or more database resources 1050 to make its determination, such as a database of compilers 1051 n and their identifications. An important aspect of cybersecurity analysis of software is determining whether or not a compiler's safety features were enabled, which is done by the compiler safety feature analyzer 1045. Modern compilers have the ability to substitute insecure functions called for in the source code with more secure versions that perform the same functions. However, if this feature is not enabled, the functions will not be substituted. Enablement of the safety features can be determined using the same methods as for compiler identification. A crash tester 1046 may be used to determine the robustness of the software to bad inputs or attempts to crash or hang the software by intentionally inputting improper or unexpected information. Further, a functional efficiency evaluator 1047 may be used to evaluate whether the software does what it purports to do, and its level of efficiency in doing so. For example, if the software is a malware detector, the functional efficiency evaluator 1047 may determine whether it functions as such, and evaluate what percentage of malware introduced into the computer system it detects and quarantines.

FIG. 11 is a block diagram showing an exemplary architecture for a hardware analyzer 1100 for a holistic computer system cybersecurity evaluation and scoring system. In this embodiment, the hardware analyzer 1100 comprises a hardware definition portal 1110, a hardware identification and configuration detector 1120, a hardware emulation environment 1130, a hardware environment analyzer 1140, and one or more database resources 1150. The hardware definition portal 1110 receives either hardware specifications 1111 to define the hardware under test or physical computer hardware 1112 (e.g., via delivery, a drobox, etc.) as the hardware under test.

Where the hardware is defined by specification 1111, the hardware may be defined by specifying the particular components that make up the hardware (e.g., the central processing unit (CPU), memory, storage, system bus, etc.), including details such as the manufacturer, date of manufacture, model number, serial number, etc., from which the performance characteristics of each part can be obtained. Alternatively, the hardware may be defined directly in terms of performance characteristics, for example specifying the bit width (or word length) of the architecture (e.g., 32-bit, 64-bit, etc.), the processor clock speed, the bus speed, and other characteristics that determine the hardware's performance. The operation of hardware defined by specification can be emulated using an emulator or virtual machine. Where physical hardware is used to define the hardware under test 1112, the actual physical computing device may be used as the hardware under test. In some cases, the physical hardware may be physically transported (e.g., delivery, drobox, etc.), while in other cases the physical hardware may be accessed and operated locally (i.e., onsite), while in yet other cases the physical hardware may be accessed and operated remotely (e.g., via a terminal associated with the physical hardware, remote device control using a different computer, screensharing, etc.).

Where the hardware is defined by specification 1111, the hardware definition portal 1110 sends the hardware specification 1111 to a hardware emulation environment 1130. The hardware emulation environment 1130 is a computing device configured to emulate the operation of the hardware defined by the specification 1111. Emulation is usually performed by running emulation software on a computer that is more powerful than the hardware being emulated, to account for the additional processing overhead of the emulator itself in addition to the processing within the emulated hardware. The hardware emulation environment 1130 comprises an operating system installer 1131, a software installer 1132, and the emulator 1133. In some embodiments, the OS installer 1131 and software installer 1132 will be part of the emulator 1133. The OS installer 1131 installs the operating system under which certain software will run. The software installer 1132 installs software to run on the hardware. When testing the hardware platform separately, this software may or may not be the software under test. For example, in some tests, the software may be a benchmarking application designed to generate artificial loads, or other functional application designed to test the operation of the hardware under test. Once the OS and software are installed, and the emulator 1133 is operating, the emulator acts as the hardware under test, and can be analyzed by the hardware environment analyzer 1140, just as physical hardware would be. The hardware emulation environment 1130 may use one or more database resources 1150 such as databases of downloadable hardware emulators 1051 d, operating systems 1051 n, etc. In some embodiments, emulation is not required at the hardware analysis stage (but may be used in a later stage when the system is evaluated as a whole), and the hardware specifications 1111 are passed directly to the hardware environment analyzer 1140.

Where physical hardware is used to define the hardware under test 1112, a hardware identification and configuration detector 1120 is run, which automatically identifies the type of hardware, its components, its performance specifications, and its configuration. Modern operating systems conduct a series of port checks and queries of hardware components attached to a computer system each device returns its device identifier (e.g., CPU ID, MAC address, etc.), which is then matched against lists of such identifiers to determine various characteristics of that hardware component (e.g., type of hardware, manufacturer, performance characteristics, size of storage, etc.). The hardware components and their characteristics can generally be obtained by querying the operating system about hardware that makes up the computer system. Where the operating system cannot identify a hardware component, the hardware component can be queried directly, and database resources 1150 external to the operating system may be used to identify the hardware component such as manufacturer websites 1151 a, hardware ID databases 1151 b, etc. Once the hardware and its configuration have been identified by the hardware ID and configuration detector 1120, operation passes to the hardware environment analyzer 1140.

The hardware environment analyzer 1140 conducts one or more analyses of the hardware. The hardware vulnerability analyzer 1141 can conduct either static evaluations or dynamic testing of the hardware for vulnerabilities. For example, the hardware vulnerability analyzer 1141 may search a number of database resources 1050 such as manufacturer websites 1151 a, hardware ID databases 1151 b, etc., to identify known vulnerabilities in the physical configuration of the hardware. For example, the most notorious hardware security flaw to date (commonly known as Spectre and Meltdown, which are variants on the flaw) was identified in 2018 and affected nearly every computer chip manufactured in the two decades prior to 2018. The flaw involved exploiting speculative execution and caching to gain access to information that was supposed to be secure. Where database results cannot be used or are inconclusive, the operation of the hardware can be tested by running operations on the hardware associated with known hardware exploits to determine whether the hardware is susceptible to such exploits. The firmware vulnerability analyzer 1142, operating system analyzer 1143, and network connectivity analyzer 1144 operate similarly, first checking database resources 1150 such as firmware updates 1151 c, operating systems, updates, and patches 1051 n, etc., to determine known vulnerabilities based on hardware components identified in the hardware under test, and performing operational testing of the hardware components in cases where the database results cannot be used or are inconclusive.

FIG. 12 is a block diagram showing an exemplary architecture for an operating system analyzer 1200 for a holistic computer system cybersecurity evaluation and scoring system. In this embodiment, the operating system (OS) analyzer 1200 comprises an OS definition portal 1210, an OS environment analyzer 1220, and one or more database resources 1230. The OS definition portal 1210 receives either operating system specifications 1211 or uses an installed operating system to define the operating system component of the system under test. In this example, definition by installation 1212 is not used, and it is assumed that the definition of the operating system 1211 will be sufficient to conduct the analysis. However, in some embodiments, testing on an installed operating system may be performed as is the case for hardware analysis above. While operating systems are software, they provide low-level functionality to allow applications to operate on the hardware.

The OS definition portal 1210 forwards the OS specifications 1211 to an operating system environment analyzer 1220, whose functions are similar in nature to those of the hardware environment analyzer 1140. The version checker 1221 may search a number of database resources 1230 such as developer websites 1231 a, OS update databases 1231 b, malware exploit databases 1231 n, etc., to identify known vulnerabilities in the operating system. A patch verifier 1223 can determine whether patches are available and/or installed for any identified vulnerabilities. Where database results cannot be used or are inconclusive, the security of the operating system can be tested by running operations on the hardware associated with known hardware exploits to determine whether the hardware is susceptible to such exploits. One area in which this capability is particularly useful is in industrial control systems, which often have older and customized/proprietary hardware and operating systems installed which cannot be upgraded without major upgrades throughout the facility. In such cases, operating tests can be conducted by the vulnerability identifier 1222 to identify security issues common on such older and/or customized systems such as whether any passwords or authentications at all are required, password length, use of group-based passwords, transmission of plain (unencrypted) text, ease of user access to low-level system operations, application access to low-level system components like the kernel, stack, and heap, and the like.

FIG. 13 is a block diagram showing an exemplary architecture for a scoring engine 1300 for a holistic computer system cybersecurity evaluation and scoring system. The separate software, hardware, and operating system analyses are fed into a system component list generator 1310, which compiles a comprehensive list of all system components (in a manner similar, for example, to a bill of materials for manufactured or constructed projects). This comprehensive list can be compared with a universal data registry 1330 to determine whether similar or identical systems have been evaluated and scored in the past, in which case the prior evaluation and scoring may be used to speed up the analysis or avoid some or all of the evaluation process. In some embodiments, the system component list generator 1310 receives a list of all identified software, hardware, and operating system components before the software, hardware, and operating system analyses are conducted, and allowing for scoring to be based on prior analyses of some or all of the components of the system under test without having to repeat those analyses. The system component list generator 1310 sends the comprehensive list of system components, the results of the software, hardware, and OS analyses and any prior evaluations and scoring from the universal data registry 1330 to a scoring adjuster 1320 for scoring.

The scoring adjuster 1320 comprises a base score generator 1321, a domain and use case modifier 1322, a system criticality 1323 adjuster, and a magnitude of risk adjuster 1324. The base score generator 1321 calculates a base cybersecurity score for the system as a whole, based on all information received by the scoring adjuster 1320. The domain and use case modifier 1322 modifies the score to account for the domain and/or use case in which the system will be used. For example, the base score of a given computer system may be adjusted downward if that computer system is to be used in the finance industry, where a greater level of security is required, and adjusted upward if the computer system is to be used in the retail industry where it will be used for the less critical purpose of tracking inventory. The system criticality 1323 adjuster may further adjust the score to account for the criticality of the system in overall operations. For example, even in the finance industry, a given computer system used primarily for document production will be less critical that the same system used to manage account passwords. Finally, the magnitude of risk adjuster 1324 may be used to further adjust the score based on the magnitude of the losses and/or damage that would occur if the computer system is compromised. For example, a small, desktop computer that stores passwords for access to online financial accounts would have a very large impact if compromised, so the score storage of such passwords on that computer cause the score to be reduced. The evaluation and scoring, component lists, and other information may be stored in the universal data registry 1330 for evaluations and comparisons with other systems.

FIG. 14 is a block diagram illustrating an exemplary architecture for an embodiment of a holistic computer system cybersecurity evaluation and scoring system configured to provide hardware exploit testing on external networks utilizing virtualized network testing. In this embodiment, the system 1400 comprises a cloud-based test host 1410 which applies hardware emulation techniques described herein to a target network 1420 while operating outside of the target network. The cloud-based test host 1410 may be a specifically configured and/or augmented embodiment of a holistic computer system cybersecurity evaluation and scoring system which, based on the configuration, provides target network 1420 virtualized testing of an entire target network comprising a plurality of hardware devices 1421 a-n and the physical and logical connections between and among the plurality of hardware devices 1421 a-n via a hardware emulator. Cloud-based test host 1410 may function as a single computing device on which to emulate an entire target network 1420, or it may function as distributed system wherein two or more computing devices are used to provide target network testing and scoring. In a distributed architecture, the two or more computing devices may be disposed in a single location (e.g., data center) or the two or more computing devices may be operating in two separate locations (e.g., a first data center and a second data center). By utilizing a cloud-based architecture, system 1400 can dynamically adapt and quickly scale to meet the processing needs that may be required to emulate an entire target network 1420.

According to the embodiment, cloud-based test host 1410 may comprise a system definition portal 901, a software analyzer 1000, a hardware analyzer 1100, an operating system analyzer 1200, and a scoring engine 1300. For more details on these system components, please refer to FIG. 9 , FIG. 10 , FIG. 11 , FIG. 12 , and FIG. 13 respectively. The system definition portal 901 provides the means for a user to define the system to be tested (also known as the “system under test”) in terms of its hardware, software, and operating system components. The software analyzer 1000 receives the definition of the software component of the system under test and analyzes it for cybersecurity issues. The hardware analyzer 1100 receives the definition of the hardware component of the system under test and analyzes it for cybersecurity issues. The operating system analyzer 1200 receives the definition of the software component of the system under test and analyzes it for cybersecurity issues. The network analyzer 1413 receives the definition of the hardware and the definition of the target network 1420 and analyzes it for cybersecurity issues. The scoring engine 1000 receives the analyses from the software analyzer 1000, hardware analyzer 1100, operating system analyzer 1200, and network analyzer 1413 performs additional checking and testing of the system under test as a whole, and assigns a cybersecurity rating or score to the system under test as a whole computing environment. Note that an operating system is a type of software, so references to software may include operating systems where the context allows.

With respect to the system definition portal 901, in this embodiment the system definition portal 901 is a stand-alone portal allowing for definition of the entire system under test (i.e., target network 1420), but in other embodiments, it may be simply be an input component of the software analyzer 1000, hardware analyzer 1100, operating system (OS) analyzer 1200, and network analyzer 1413. Each of the software, hardware, and operating components of the system under test can be defined in several ways. One primary method of definition is specification of the component's parameters. For the hardware component, for example, the hardware may be defined by specifying the particular components that make up the hardware (e.g., the central processing unit (CPU), memory, storage, system bus, etc.), including details such as the manufacturer, date of manufacture, model number, serial number, etc., from which the performance characteristics of each part can be obtained. Alternatively, the hardware may be defined directly in terms of performance characteristics, for example specifying the bit width (or word length) of the architecture (e.g., 32-bit, 64-bit, etc.), the processor clock speed, the bus speed, and other characteristics that determine the hardware's performance. The hardware may be defined using memory maps. Memory maps are used to associate hardware components of a physical hardware system (e.g., hardware devices 1421 a-n) and memory locations of the virtualized system. In other words, a memory map reproduces the memory locations used by the physical hardware of the target network 1420 to exchange information while also describing the connections between components of the physical hardware system of target network 1420 from a memory interface perspective. For example, a memory map can represent locations of information for memory registers of hardware devices 1421 of the target network 1420 as an offset from the starting memory address. Furthermore, a hardware device may be defined by the interrupt logic which can be information describing the interrupt functionality of the hardware devices 1421 a-n.

For hardware, in particular, definitions by specification may be useful as the actual hardware may not be available or may difficult to obtain, yet can often be emulated using an emulator or virtual machine. Similar definitions by specification can be made of software and operating systems, for example specifying the software name, version, etc., from which operating characteristics may be identified, or by directly specifying the operating characteristics. While it is possible to emulate or simulate the operation of software, this is typically not done as the software is usually readily available. A second method of definition is provision of the actual software, hardware, and/or OS to be tested. For example, software and operating systems can be uploaded, the actual hardware to be tested may be provided, and in some cases the entire system may be provided for testing with the software and operating system already installed on the hardware. Where physical hardware is used to define the hardware under test, the actual physical computing device may be used as the hardware under test. In some cases, the physical hardware may be physically transported (e.g., delivery, drobox, etc.), while in other cases the physical hardware may be accessed and operated locally (i.e., onsite), while in yet other cases the physical hardware may be accessed and operated remotely (e.g., via a terminal associated with the physical hardware, remote device control using a different computer, screensharing, etc.).

Cloud-based test host 1410 further comprises a system test portal 1411 an automated defensive strategy and analysis module 1412. System test portal 1411 provides the means for a user to define the test case to be tested on the target network 1420. Additionally, or alternatively, system test portal 1411 can allow for a user to configure a virtual machine and upload it to cloud-based test host 1410. Cloud-based test host 1410 can create a plurality of virtual machines based on the user configuration, thereby enabling the system 1400 to dynamically scale with the size of the target network. In some implementation, a set of clones of an emulated device, system, or network are created and tools are injected in each clone for testing. Automated cybersecurity defensive strategy analysis and recommendation module 1412 may be utilized to perform various tasks. For example, automated cybersecurity defensive strategy (ACDS) analysis and recommendation module may be leveraged to provide: simulated/emulated representations of a target network under test; a network score based on test results and analysis thereof; and the capture of system characteristics and information about the operation of the network under test during exploit testing. ASDS module 1412 may comprise a reconnaissance engine configured to capture network information about a target network 1420. The network information may comprise system information and characteristics generated by target network 1420 nodes (i.e., hardware devices, resources) associated with the target network 1420. ACDS module 1412 may leverage a cyber-physical graph which is used to represent a completer picture of an organization's infrastructure and operations, including, importantly, the organization's computer network infrastructure. Target network information captured by reconnaissance engine and the device classifications it generates may be used by hardware emulator or a machine learning simulator to create an accurate virtualized model of the target network 1420. ACDS module 1412 may also function as a centralized test generation and deployment mechanism wherein ACDS module 1412 can receive user submitted test cases from system test portal 1411 or use a plurality of tests and tools stored in the module to perform exploit testing on the target network 1420. In some implementations, the exploit testing comprises penetration testing.

Target network information may be used to define a target network and sent to network analyzer 1413 which may also receive hardware definitions from system definition portal 901 and use this information to establish a network cybersecurity score. The network cybersecurity score may be used an input into scoring engine 1300 to generate an overall cybersecurity score for a target network 1420. In some implementations, network analyzer 1413 or the functionality it provides may be integrated with ACDS module 1412, wherein the ACDS module 1412 performs automated testing and analyzes an entire virtualized target network's response to the test, and outputs a risk score which measures the vulnerability of the target network to an exploit or compromise. The risk score can be used as a network cybersecurity score which can then be fed into scoring engine 1300 as an input to determine an overall cybersecurity score for the target network 1420. For more detailed information regarding ACDS module 1412 please refer to U.S. patent application Ser. No. 17,567,060, the entirety of which is included herein by reference.

According to the embodiment, the system is configured to provide hardware exploit testing on external networks. In some implementations, the hardware exploit testing on external networks is provided by applying the hardware emulation techniques described herein to networks from testing hosts operating outside the target network. Testing the hardware components of a network (e.g., modems, Ethernet hubs, network switches, routers, etc.) and the connections between and among the hardware components can provide a few benefits. For example, using an external testing host 1410 provides ease of management and ease of deployment because it does not require a network connected resource (e.g., a computing device, hardware component, etc.) to be identified to be used as a host for the emulated environment and as a result there is no need to create tests on the machine where the emulation will occur. System 1400 leverages the fact that while emulation of hardware components is host-specific; test case needs are not. As a result, system can provide for centralized test generation and deployment to one or more target networks and/or one or more hosts in a target network.

Centralized test generation and deployment can be used to scale up the testing capabilities of the system as well as to provide test cases to various and/or multiple targets. In some implementations, system can implement modular test case components such that a user can create a test case. Examples of modular test case components may include, but are not limited to, known exploits the user wishes to test for and against, known hardware the user wants to include or not include in a test case, plug-and-play hardware configurations using known components (configurations may be user inputted, or obtained from database resources 1150 which provide hardware configuration information), and/or preconfigured rules that indicate dependencies and processes that govern interaction between hardware, software, and/or applications (e.g., Operating System, etc.). The test cases may be stored in a database and retrieved when a particular test case has been selected to be used to test the target network. Test cases can be used on various/multiple targets to improve testing speed and throughput. For example, system can allow for testing of multiple hosts in a target network with a single test case, allow for the testing of multiple networks using a single test case, or allow for scheduled testing to see if countermeasures (e.g., output recommendations) are working or if the patches have been deployed properly. In some implementations, a user, such as a customer of a cloud service, can configure an initial test virtual machine on a cloud platform. One or more components of the cloud architecture can then scale to test the service/software/hardware by creating multiple tenant virtual machines with the user configuration, can run tests, and can report results.

According to the embodiment, system 1400 is configured to provide virtualized network testing by emulating a target network 1420 hardware 1421 a-n and connections (e.g., both physical and logical) between and among the network hardware. An hardware emulator or machine learning simulator can be leveraged to virtualize entire networks in a testing environment (e.g., cloud-based test host 1410) which provides an isolated, virtualized sandbox, then safely attack them using various attack and exploit vectors. Emulating network hardware allows the same hardware exploit testing as described herein, but with specialized hardware components and embedded system. Network emulations enable broad testing of network attacks and various compromises such as, for example, Kerberos attacks, database attacks, and man-in-the-middle attacks, to name a few. Additionally, using virtual hardware and virtual networking gives a more complete picture with a virtualized sandbox. For example, a user (e.g., individual or enterprise) may wish to know how different attacks work together to compromise a network, which is difficult if not near impossible to tell from testing a single virtual machine. As another example, using only discrete testing of virtual hardware to identify how an attacker would daisy-chain attacks to get what they want is impossible because to properly test for this scenario multiple virtual machines are needed with different hardware all connected as they would be in a live system.

FIG. 15 is a flow diagram illustrating an exemplary method for emulating, testing, and scoring a target network using a cloud-based test host. According to the embodiment, the process begins at step 1502 when a hardware emulator receives, retrieves, or otherwise obtains hardware definition(s) for a plurality of hardware devices 1421 a-n of a target network 1420. Hardware definitions may comprise operating components, performance characteristics, and/or memory maps associated with one or more of the plurality of hardware devices 1421 a-n. Hardware emulator may also receive, retrieve, or otherwise obtain target network definitions from ACDS module 1412 or one of its components such as a reconnaissance engine at step 1504. Target network definitions may comprise network information and characteristics. Target network definitions may be used to create a cyber-physical graph representation of the target network, wherein the nodes of the graph represent hardware devices 1421 a-n and resources, and wherein the edges of the graph represent connection and dependencies between and among the hardware devices of the target network. At step 1506 hardware emulator uses the hardware definitions and network definitions to emulate the target network in secure, isolated virtual test environment (i.e., cloud-based test host 1410). The emulated target network may be represented on a virtual machine or machines operating in a cloud environment of a cloud-based service provider. Once the entire target network, including the plurality of hardware devices 1421 a-n and the connections between and among the network devices, have been emulated the next step 1508 is to perform a test on the emulated target network. Tests may be configured to execute an attack associated with a known hardware exploit on the emulated target network. In some implementations, the test performed on the emulated target network may comprise a penetration test. Furthermore, a penetration test may be performed on a live network and the response by the live network to the penetration test may be used as an input to create a network definition, which can then be used to emulate a virtualized version of the live network (i.e., the target network 1420).

Hardware emulator at step 1510 can use the hardware definition and the test results to analyze the target networks response to a hardware exploit test. Based on this analysis, hardware emulator can determine a network cybersecurity score at step 1512, which can be sent to scoring engine 1300 to be used as an input to update the overall cybersecurity score for the target network 1420 at step 1514. According to this embodiment, system 1400 can provide holistic network cybersecurity evaluation and scoring using a test host system operating outside the target network.

It will be appreciated by one having ordinary skill in the art that any combination of known or future database technologies may be used as appropriate, unless a specific database technology or a specific arrangement of components is specified for a particular aspect described herein. Moreover, it should be appreciated that the term “database” as used herein may refer to a physical database machine, a cluster of machines acting as a single database system, or a logical database within an overall database management system. Unless a specific meaning is specified for a given use of the term “database”, it should be construed to mean any of these senses of the word, all of which are understood as a plain meaning of the term “database” by those having ordinary skill in the art.

Similarly, some aspects may make use of one or more security systems 36 and configuration systems 35. Security and configuration management are common information technology (IT) and web functions, and some amount of each are generally associated with any IT or web systems. It should be understood by one having ordinary skill in the art that any configuration or security subsystems known in the art now or in the future may be used in conjunction with aspects without limitation, unless a specific security 36 or configuration system 35 or approach is specifically required by the description of any specific aspect.
